more particularly to that class of the same in which the button is provided with an elastic collet, and its fundamental vfeatures are illustratedand described inmy coending application Serial No. 8494171, led July 7, 1914-. The object of my invention is to construct a button of this character in which` the collet will co-actwith a slotted base plate to fasten the button tape to the button. A further Object is to construct a button in which the collet is so shaped that it will present oppositely disposed `faces which will coact with the button loop to fasten the l attain these and other objectsof my in vention in the device set `forth in the following description and accompanying drawings in which like reference characters `refer to y corresponding parts.

ln the drawings:

Figure 1 is a front view of one form of bllittm clasp to which my invention is app Fig. 2, a central longitudinal section taken on line aas-w in Fig. 1 but showing the button loop swung forwardly out of engagement with the button;

Fig. 3, a detail view showing the manner in which the button is threaded before it is attached to the clasp;

Figs. 4 and 5, detail views of a modification; and

Fig. 6, a detail view of a further modication.

The button clasp generally consists of an attaching link A, a button loop B and a button tape C which carries a button D at its lower extremity. rlhe button loop B, which is connected to the lower side of the attaching link A by a strap E projecting from the upper side thereof, is provided with a bridge F and hasthe sides of its lower extremity contracted to engage the shank ofthe button D. With the exception of the button D and the manner of attaching the same to the Specification of Letters Patent.

tape C, the device thusfar described .is one of the coinmonforms of button clasps well known in the art and herein for the purpose of showing how my invention is applied. Referring to Figs. `1, 2 and 3, the button D consists of a base plate 2 to which is riveted an outwardly projecting stud 3 provided `with a head 4:. Slipped over the stud 3 and held against the base by the under side of the headll is an apertured `is merely disclosed spring rubber collet 5 which is shaped to form a headV 6, a neck or shank 'T and a flange 8. The under side of the head 6 and the upper side of the liange 8 are spaceda predetermined distance apart to present oppositely disposed faces 9 and 10 respectively. The under side of the `Hange 8 overlaps the slots 11 and 12in the base plate 2 so that the periphery or edge of the ange will nearly close the middle portion of the slots leaving the ends of the slots is threaded withtape by inserting one corner of the end 13 of the tape rearwardly through open. rllhe base plate 2 v one of the open ends of the lower slot 11. y

pulled throughthe slot from its' rear side and passed forwardly through the upper slot 12 overlapping edge of the flange 8 will yield sufficiently to permit the passage of the tape. The flange 8, however, is suhciently resilient to co-act with the outer edges of the slots to grip the tape and fasten it to the button. The tape is secured to the clasp by passing its end 14 forwardly through the link A, then rearwardly through the loop E over the top of the bridge Fl. Both ends 13 and 14 are then fastened together by stitches 15, 15, the end 13 being folded in to prevent fraying. The neck 7 and the Oppositely disposed faces 9 and 10 of the collet co-act with the upper `and lower faces and the inner edge of the loop B, which is shown made of sheet metal, to grip the stocking or other garment.

Referring to Figs. fl and 5, wherein the collet is shown made in two pieces, the flange 16 projects beyond the slots thereby present ing a greater gripping surface 17 on its under side. lts top side is provided with a seat 18 for the reception of the lower end of the neck 19 depending from the head 20. lln

ina like manner. During the threading of the base plate the* It should be observed that the utilization of the' elastic collet of the character above described enables me to secure the tape to the button without stitchin'g'the same at itsv button end unless desired, and further kwhen the parts are assembled by slipping the collet overt-he head of the stud, which is the preferred' way of assembling7 the operation can be performed by hand; It' should be noticed also that the flange of the collet substantiallj7 conceals the' metald between the slots in the base thereby enhancing the appearance of .the button.

Referring to Fig. 6, the collet 23" has the periphery of its flange 24 undercut or rounding off on its underl side so that theV overlappingedges of the flange do not obstruct the; free passage of the folds in the tape when it is desiredto fasten the latter by sewing.

I have herein referred'touthe collet asbeing made' ofv spring or elasticrubberybut my invention is intended toinelude all like collets made of'other elastic or springy material.

While the preferred formsl of my invention are embodied in the devicesabove described; -yet the same are susceptible to such further` modifications as may fairly ent is: l

1. A button clasp comprising a loop and l button, the said button being provided with a stud and anjelasticl collet mounted onsaid studj the'said' collet having oppositely dis'- (logies of' 'this-patent mayV bef obtained.l for come within the scope .of the appended Having now described my invention what l posed faces spaced apart by an elastic neck and the said faces being arranged to co-act with the upper and lower sides of the loop.

2. A button for button clasps comprising a slotted base plate provided with a projecting stud, fabric material threaded through said base plate and an elastic collet having a neck surrounding said stud, the said collet beingV provided with` an outwardly projecting flange at its lower extremity which overlapsthe slotsand co-acts-with said base plate to grip the fabric material.

3. In a button cla-sp a button comprising a slotted base plate on which is mounted a headed stud, the said base plate being threadedwith tape, and an elastic collet surrounding said stud and held against the tape by the under side of the head of the stud, the

y saidV collet being provided with oppositely V disposed co-acting faces spaced apart by a neck.

4. A button for button clasps comprising a slotted-base plate, a tape passed through said slots', a stud projecting from the face of said base plate between the slots, an annular elastic disk slipped over said stud, the diameter 0f said disk being greater than the distance between the slots, and an elastic collet having a shank and head surrounding said stud in front of said disk, the said elastic members filling the space between the base and the head of the stud.

1n testimony whereof I have hereunto set my hand this 27th day of July 1916.
